Solution to: Transport dt_socket failed to initialize

Hey, this is aplicable in Windows systems, JDK 1.3.1

I kept finding this error trying to initialize the JPDA. The solution is to copy the dt_socket.dll file from the jre/bin dir into the current working dir. I'm not a DLL guru, but I think it's the same as to copy it to the system dir.

I'm not sure how to do it, so someone please send this to the JPDA FAQ or the bug lists.

Regards to all :)

I copied it to system32 directory, and that worked just fine.. there are two files of interest..dt_socket.dll and dt_shmem.dllone is for remote debugging and the other for local.Good Luck

I am having trouble starting JBoss with the -Xrunjdwp option. Here is my command line:

java -classic -classpath "%JBOSS_CLASSPATH%" -Xdebug -Xnoagent %JAXP% -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=8787,server=y,launch="c:\Together\bin\win32\display.bat c:\Together",suspend=n org.jboss.Main tomcat

I get the error:

JBOSS_CLASSPATH=;run.jar;../lib/crimson.jar

Transport dt_socket failed to initialize, rc = 510.

FATAL ERROR in native method: No transports initialized

abnormal program termination

I found some mention of this error on the sun web site which suggested putting dt_socket.dll in the winnt/system32 directory, but this doesn't work.

I'm running jdk1.3.1_01 and C:\jdk1.3.1_01\bin is at the beginning of my path.

Any suggestions?

I copied those files to my System32 and it didn't do a single thing! I still get this error:

Socket transport failed to init.

Transport dt_socket failed to initialize, rc = -1.

FATAL ERROR in native method: No transports initialized

I am using port 1151. Any useful suggestions?

Make sure that "<java_home>\bin" is in your path.You dont need to copy the dll anywhere as it will be found along the path.

crowleym at 2007-6-29 12:55:21 >

# 5

Thats not going to help as System32 was already in the path and it did not work. Besides, I do have <JAVA_HOME> /bin in my path. Is there a conflict with Forte?

jamestthomas at 2007-6-29 12:55:21 >

# 6

I was also getting the dt_socket error and after approx 2 hours of digging have got it working.- I added .\jre\bin to my PATH : Still got error.- Copied dt_socket.dll to my system32 folder : All okay.Am running 1.3.1.02

have checked whether the dll is registered or not? It doesnt matter where the dll resides the only thing that matters is whether that dll is registered or not.use regsvr. first uninstall it the install it

The runtime can't find the JPDA libraries dt_shmem.dll

and dt_socket.dll. Please double-check to be sure

they are in a directory that is on your PATH.

Bug 4420211 addressed this in 1.4.0:

http://developer.java.sun.com/developer/bugParade/bugs/4420211.html

As a side note, jdk1.2.2 is a very old release

of the technology. I suggest you download and

install 1.4.1 from this web page:

http://java.sun.com/j2se/1.4.1/

I am also using linux / JDK_141 and am attempting to debug with Eclipse however, when I start Tomcat I get the following error:

Transport dt_socket failed to initialize, rc = -1

<jdk14>/bin is in the path

Any other suggestions?

The reason is the same- the dt_socket library could not be located. Some of the other users succeeded by placing the %JAVA_HOME%\bin in their path, because the Java SDKs for Windows, version 1.3.1 or higher, include the dt_socket.dll and dt_shmem.dll.

Find where the dt_* libraries are located on your Linux distribution, and make sure that Eclipse starts the Tomcat server providing the PATH environment var that would list the location of the dt_* libs.

I got the same problem with rc=509, in Windows XP environment using Java 1.4.2. I solved the problem by putting <java_home>/jre/bin as the first entry in my PATH. With only <java_home>/bin in my path I encountered the mentioned problem.

Stupid me....i got the same error while i tried to debug my project and tried ev'rything all of you suggested.

it didn't work out.....BUT finally i solved the problem.

Due to the fact that Eclipse uses the IP protocol in debug mode I disabled my firewall and guess what...i worked.. ;-)

maybe I could help some of you..

cheers

Just for the record, I got the same problem when I installed Java 5, but wanted to run Tomcat using 1.4.2.The fix was simply to change the catalina.bat file to explicitly set the path to find where 1.4.2 was installed as well as the path to dt_socket.dll.

Hi all,

i am using weblogic 8.1 i am trying to install it but i am getting this error message on the console

Error [2] in bind() call!

err:: No such file or directory

Socket transport failed to init.

Transport dt_socket failed to initialize, rc = -1.

ERROR: No transports initialized

please suggest any solution.

I guess you should set up all the options. Listed below is an example.-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=3333

chesterwoo at 2007-7-1 10:09:20 >

# 22

The port 3333 is probably in use by another program. Try changing the portnumber.

I had the same issue and found the resolution in this thread...the problem is gone once I remove the debug port; pls suggest how to add the same port again since it is configured in my IDE for remote debugging

code-a-rama at 2007-7-1 10:09:20 >

# 24

yeap, copying files into system directory or/else setting the path does solve this problem.i traced it with the io spy. it seems to occur when multiple JVMs are installedthanks to whoever observed this first and posted.

I encountered the same problem. My environment is:

JAVA version = 1.4.2_13

JAVA_HOME = C:\j2sdk1.4.2_13\bin

IDE = Eclipse 3.2

Web Server = Tomcat 5.0.28

I solved this by copying the two dll files (dt_shmem.dll, dt_socket.dll) from "C:\j2sdk1.4.2_13\jre\bin" to "C:\j2sdk1.4.2_13\bin".

Hope it is helpful.
